Couple charged with felony for chaining teen

SACRAMENTO, Calif. 
Prosecutors say a Sacramento couple has been charged with felony child endangerment for imprisoning their 13-year-old son for days by locking him in chains, often tethered to a kitchen table.

Forty-one-year-old John Vang, the teen's father, and 34-year-old Thong Vue, the boy's stepmother, appeared for arraignment Monday in Sacramento Superior Court, but they didn't enter a plea. They will return to court Aug. 18.

The couple is free on bail. They wouldn't talk to reporters.

Investigators say the boy was wrapped in chains - with padlocks securing each ankle and a long chain connected to the padlocks - for days until he managed to escape July 30 and flag down passers-by for help.
